When one has only one cup of wine for the entire Shabbat, how should it be allocated between Friday night Kiddush, Shabbat day Kiddush, and Havdalah?

ShabbatKiddush

Synopsis

The Mechaber rules: use it for Friday night Kiddush, pour into a second cup to drink from, and use what remains the next day. If wine is insufficient for both daytime Kiddush and Havdalah, Havdalah takes priority over day Kiddush since Havdalah cannot be made on bread. Tosafot and Magen Avraham disagree, holding Friday night Kiddush always takes priority over Havdalah.
